Abstract

According to the present invention, a media file reproducing apparatus reads mapping information from a predetermined location in a media file, searches for a sound field effect file by referring to the mapping information, By setting the equalizer according to the searched sound field effect file, the user can reproduce the media file using the equalizer optimized for each of the media files in advance without setting the equalizer manually, It can be appreciated under the same reproduction environment.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for setting an equalizer in a media file reproducing apparatus,

The present invention relates to a method for reproducing a media file, and more particularly, to a method for setting an equalizer when reproducing a media file including audio data.

In general, the equalizer function is basically provided in a device that plays media files such as music or video. The user can reproduce audio data according to his / her taste by amplifying or reducing the size of a specific frequency band using the equalizer function.

FIG. 1A is a diagram for explaining an equalizer setting method according to the related art. In a general digital audio apparatus, when a user attempts to set an equalizer, a screen such as that shown in FIG. 1A is displayed first. As shown in FIG. 1A, the user can select one of preset menus according to music genres such as <classic>, <jazz>, <dance>, and <house> to apply various equalizer setting values to listen to audio data can do.

If the preset menus are not suitable for the user's taste, the user can select a menu such as &lt; user EQ &gt;, and manually adjust the amplitude thereof for each frequency band. When the user selects the &quot; user EQ &quot; menu, the media file playback apparatus provides a user interface as shown in FIG. 1B through the display device.

However, according to the conventional art, once the equalizer is set up, the same applies to all media files until the user changes the settings. Therefore, if the user wishes to listen to music of various genres using the optimized equalizer setting value, it is inconvenient to directly set the equalizer every time the music is changed. In addition, when the user finds an optimized equalizer setting value, there is no way to directly apply the equalizer setting value that was previously used when the same media file is to be viewed by another reproducing apparatus. Therefore, the equalizer must be reset there is a problem.

An object of the present invention is to provide an apparatus and method for setting an equalizer for each file when reproducing a media file.

According to an aspect of the present invention, there is provided a method of reproducing a media file including audio data, the method comprising: reading mapping information from a predetermined location in the media file; Searching the sound field effect file for the media file by referring to the mapping information; And setting an equalizer for the audio data based on the sound field effect file.

The reproducing method may further include recording the mapping information at the predetermined position of the media file.

The reproducing method includes extracting an equalizer setting value while reproducing the media file or a media file other than the media file; And generating the sound field effect file using the extracted equalizer setting value.

Further comprising the step of selecting one of a plurality of sound field effect files indicated by the plurality of mapping information according to an input of a user when the read mapping information is plural, It is preferable that the selected sound field effect file is a selected sound field effect file.

The mapping information may include information indicating a location of the sound field effect file in a directory structure of the media file reproducing apparatus.

The mapping information may include a Uniform Resource Locator (URL) of the sound field effect file.

The present invention also provides a recording medium on which a computer program for executing the above-mentioned reproducing method is recorded.

According to another aspect of the present invention, there is provided an apparatus for reproducing a media file including audio data, the apparatus comprising: a mapping information reading unit reading mapping information from a predetermined location in the media file; A file search unit for searching a sound field effect file of the media file by referring to the mapping information; And an equalizer setting unit for setting an equalizer for the audio data based on the sound field effect file.

The reproducing apparatus may further include a mapping information recording unit for recording the mapping information at the predetermined position of the media file.

According to the present invention, a user can play a media file using an equalizer optimized for each media file in advance, without manually setting the equalizer.

In addition, since the equalizer setting values set by one reproducing apparatus can be applied to other reproducing apparatuses as they are, it is possible to enjoy one media file in the same reproducing environment in different reproducing apparatuses.

In addition, since the sound field effect file can be shared through the web, the user can enjoy the same equalizer setting value set by a third person with respect to one media file.

2 is a flowchart illustrating a process of setting an equalizer when a media file is reproduced according to the present invention. Here, the media file should be broadly interpreted as including all the media files including audio data such as a music file as well as a moving picture.

In step 210, the media file playback apparatus receives a playback command for a specific media file from the user.

In step 220, the media file playback apparatus reads the mapping information from a predetermined position of the media file. The media file reproducing apparatus according to the present invention sets the equalizer differently for each media file, and the equalizer setting value for the media file is stored in a file separate from the media file. Hereinafter, this is referred to as a sound field effect file.

In order to find the sound field effect file to be applied to the reproduction of the media file, mapping information indicating the position of the sound field effect file is required. This mapping information is recorded at a predetermined position in the corresponding media file. That is, the predetermined location is a reserved area for recording the mapping information in the media file, and a user area designated in a media format of various standards in general can be used for this purpose.

Meanwhile, the sound field effect file to be applied to the media file, that is, mapped to the media file, may be stored together with the media file reproducing apparatus in which the media file is stored, or may be stored in another external device. Therefore, in the case of the former, the mapping information may include information indicating the location of the sound field effect file in the directory structure of the media file reproducing apparatus. In the latter case, the mapping information may include a URL (Uniform Resource Locator) have.

According to an embodiment, a plurality of mapping information may be recorded in one media file. It is considered that the setting value of the equalizer may be optimized depending on the apparatus reproducing the media file. In this case, the media file reproducing apparatus displays a plurality of mapping information or a name of the sound field effect file corresponding to each mapping information to the user, and selects one of the sound field effect files from the user.

In step 230, the media file playback apparatus searches for a sound field effect file. If a plurality of mapping information is read out in step 220, the sound field effect file selected by the user is searched.

If the mapping information is stored in another device, the media file playback apparatus accesses a home network, the Internet, or the like to search for a sound field effect file.

In step 240, the media file playback apparatus analyzes the sound field effect file found as a search result and sets an equalizer.

In step 250, the set equalizer is applied to play the media file.

3 is a flowchart illustrating a process of generating a sound field effect file according to the present invention.

In operation 310, when the user inputs a command by pressing a specific button during playback of the media file, the media file playback apparatus extracts the equalizer setting values currently being applied to playback.

In step 320, a sound field effect file is generated using the extracted equalizer setting values.

At step 330, by the user's input, the media file reproducing apparatus records mapping information for the sound field effect file generated at step 320 at a predetermined position in the media file. Here, a user creates a sound field effect file using an equalizer setting value manually set by the user while playing the media file, maps the sound field effect file and the corresponding media file (records the mapping information in the corresponding media file) The media file in step 310 and the media file in step 330 may be different files. That is, since any sound field effect file can be applied to a media file, it is a matter of the user's choice to select any sound field effect file. For example, a user can listen to the music of "Metallica" stored in his mp3 player using a sound field effect file provided on the "Metallica" homepage on the Internet.

4 is a diagram illustrating a structure of a media file reproducing apparatus for setting an equalizer according to the present invention.

4, the media file reproducing apparatus 400 according to the present invention includes a user interface 410, a mapping information recording unit 415, an extracting unit 420, a file generating unit 430, a storage unit 440 A mapping information reading unit 450, a selecting unit 460, a file searching unit 470, an equalizer setting unit 475, and an equalizer 480. Of course, a digital / analog converter (DAC), a decoder, a synthesizer, and the like will be further included, but components that are not closely related to the present invention are omitted.

When the user inputs a command to generate a sound field effect file for the current playback environment through the user interface 410 while the user is viewing the media file through the media file playback apparatus, the extraction unit 420 extracts the currently applied equalizer setting value And extracted from the equalizer 480.

The file generating unit 430 generates a sound field effect file using the extracted equalizer setting value. The storage unit 440 is a means for storing a sound field effect file, a media file, and the like.

When the user inputs a reproduction command for a specific media file through the user interface 410, the mapping information reading unit 450 reads the mapping information at a predetermined position in the corresponding media file. If there are a plurality of pieces of the read mapping information, the selecting unit 460 selects one mapping information, i.e., one of a plurality of sound field effect files mapped with the media file, according to the input of the user.

The file searching unit 470 searches the sound field effect file by referring to the mapping information read from the media file by the mapping information reading unit 450 or selected by the selecting unit 460. [ If the corresponding sound field effect file is located in the media player 400, the storage unit 440 will be accessed. In some cases, the sound field effect file may be retrieved by accessing the Internet or a home network.

The equalizer setting unit 475 analyzes the sound field effect file found in the file search unit 470 and sets the equalizer 480. This equalizer is applied to the playback of the media file that the user wants to play.

The media file reproducing apparatus 400 shown in FIG. 4 may be implemented in a module in a PC as well as a portable device, or may be implemented in software.

5 is a flowchart illustrating a method of playing a media file according to an embodiment of the present invention.

Here, it is assumed that a user plays a media file using a PC, and then attempts to play the same media file again on his / her portable device by applying the same equalizer setting value. It is also assumed that the user's portable device does not have a networking function.

In step 501, a user who finds an equalizer setting value that is considered optimal in the "beatles-yesterday.mp3 " file he / she hears commands an application program to create a sound field effect. The PC creates a sound field effect file "beatles-yesterday.eql" using the currently applied equalizer settings.

In step 502, the PC records the location information of the corresponding sound field effect file, i.e., "beatles-yesterday.eql" in the user area in "beatles-yesterday.mp3 " For example, the mapping information at this time may be in the format "C: /music/eq_settings/beatles-yesterday.eql". That is, the mapping information at this time indicates the location of the mapping information in the directory structure in the PC.

In step 503, the user connects his / her portable device to the PC and inputs a command to copy "beatles-yesterday.mp3" to his / her portable device. The portable device at this time may be a PDA, a PMP, an MP3 player, or the like.

In step 504, the PC copies "beatles-yesterday.mp3" and "beatles-yesterday.eql" together to the user's portable device.

At step 505, the PC is copied at step 504 to change the mapping information of "beatles-yesterday.mp3" stored in the mobile device. That is, information indicating the position in the PC is changed to information indicating the position in the portable device. For example, change "C: /music/eq_settings/beatles-yesterday.eql" to "../EQ/beatles-yesterday.eql".

In step 506, the portable device receives a playback command for the user "beatles-yesterday.mp3 ".

In step 507, the portable device refers to "../EQ/beatles-yesterday.eql" to search for the sound field effect file "beatles-yesterday.eql ", and sets the equalizer accordingly.

In step 508, the portable device refers to "beatles-yesterday.eql" and applies the set equalizer to reproduce "beatles-yesterday.mp3 ".

This embodiment is useful when the portable device has no networking function because both the media file and the sound field effect file mapped thereto exist in the portable device.

If the portable device has a networking function, it is not necessary to copy only the media file and the sound field effect file in step 504, and step 505, which is a step of changing the mapping information, may be omitted. However, in this case, the mapping information should not be information indicating only the position in the directory structure of the PC such as "C: /music/eq_settings/beatles-yesterday.eql", and the URL (Uniform Resource Locator) of the sound field effect file stored in the PC Should include.

6 is a flowchart illustrating a method of reproducing a media file according to another embodiment of the present invention. As in FIG. 5, in this embodiment, a user plays a media file using a PC and applies the same equalizer setting value to the same media file to reproduce the same media file on his / her portable device. However, the user's portable device has a networking function.

In step 601, the PC receives an instruction to copy a specific media file from the user to the portable device. The sound field effect file mapped to this media file is provided by the remote web server, and thus the mapping information recorded in the media file is the URL of the sound field effect file.

In step 602, the PC copies the media file to the portable device.

In step 603, the portable device receives a reproduction command for the copied media file from the user.

In step 604, the portable device recognizes that the mapping information is a URL and accesses a web server through the Internet to search for a sound field effect file. When the portable device finds the sound field effect file stored in the web server, it reads the equalizer setting value from it, and it is not necessarily necessary to download the sound field effect file itself.

In step 605, the portable device sets the equalizer according to the sound field effect file provided by the web server (605).

In step 606, the set equalizer is applied to reproduce the media file designated by the user.

The above-described embodiments of the present invention may be embodied in a general-purpose digital computer which can be embodied as a program that can be executed in a computer, and which operates the program using a computer-readable recording medium.

The computer readable recording medium may be a magnetic storage medium such as a ROM, a floppy disk, a hard disk, etc., an optical reading medium such as a CD-ROM or a DVD and a carrier wave such as the Internet Lt; / RTI &gt; transmission).

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
